m BY $3M Patented Nov. 19, 1935 UNITED STATES PATENT OFFICE 11 Claims.

This invention relates to window assemblies and more particularly to fixed and adjustable closures used in connection with detention and semi-detention windows.

An object of this invention is to provide a screen for a closure that is readily removable by those in authority but not so by unauthorized persons.

Another object of this invention is to provide a closure for the ventilating area that is frictionally held in adjusted position.

Another object of this invention is to provide a screen for a ventilating area in a detention window that is provided with detention bars removable with the screen. H

Another object of this invention is to provide a screen and closure assembly for a detention window that is cheap, that is dependable, efficient and easily constructed with a minimum amount of labor.

Another object of this invention is to provide frictional means for holding the closure in adjusted position.

Another object of this invention is to provide increased protection to the more vulnerable area of the window assembly.

With the above primary and other incidental objects in view, as will more fully appear in the specification, the invention consists of the features of construction, the parts and combinations thereof, and the mode of operation, or their equivalents, as hereinafter described and set forth in the claims.

In the drawings, Fig. 1 discloses a fragmentary elevation of a detention window showing the ventilating area with a portion of the screen broken away. Fig. 2 is an enlarged sectional view taken on the line 2-2 of Fig. 1. Fig. 3 is an enlarged sectional View taken on the line 3-3 of Fig. 1. Fig. 4 is a sectional view taken on the line 4-4 of Fig. 3. Figs. 5 and 6 disclose detail views of the latch assembly. Fig. 7 is a sectional View taken substantially on the line l'| of Fig. 3. Fig. 8 discloses another modification of the closure assembly. Fig. 9 is an enlarged fragmentary sectional View taken on the line 9-9 of Fig. 8.

Fig. 12 is a view of the latch disclosed in Fig. 8. Fig. 13 is a fragmentary sectional view taken on the line l3-|3 of Figs. 3 and 8. Fig. 14 is an enlarged sectional view taken near the latch disclosed in Fig. 12.

In penal institutions, insane asylums, hospitals, orphanages and the like it is oftentimes desirable to provide a window that is of a semi-detention nature which will deter the free movement of objects through the ventilating area and also the free escape of the inmates. In the present invention this has been accomplished by the use of a screen that is hooked and locked in position with respect to the ventilating area, the screen carrying additional detention bars extending across the more vulnerable portion of the window which prevents the inmate from escaping in case the screen is torn or otherwise removed. In order to prevent the removal of the screen the screen frame is preferably padlocked.

It is also desirable to provide a closure for the ventilating area that may be frictionally held in adjusted position without the use of latches or other locking devices. plished by providing a spring pressed member that frictionally prevents the easy and free movement of the closure but permits the adjustment thereof. When the closure is in closed position a latch that is cheap and efiicient has been provided for locking the closure so as to prevent the same from blowing open.

Like reference numerals indicate like parts throughout the several figures of the drawings.

A plurality of transversely arranged muntin bars I0 divide the window into a plurality of spaces some of which are glazed, leaving a group of spaces l2 vacant for a ventilating area. The muntin bars l0 preferably extend across the ventilating area.

As may best be seen by referring to Figs. 2, 3 and 8, a screen l4 carried by a frame I6 is arranged to extend over the ventilating area so as to prevent the unauthorized passing of objects through the ventilating area and so as to prevent or deter escape therethrough. In addition thereto the screen serves as a tell-tale in case attempts are made to cut the duo-functional muntin bars, as'these also function as detention bars. The screenframe I6 carries hooks l8 arranged in hooked relation with the muntin bar If] extending along one side of the ventilating area. The opposite side of the screen frame It is carried by hook shaped members suitably attached to the opposite muntin bar It. One or more of the detention bars 22 supported by the screen frame It is arranged in spaced relation with the muntin bar l0 and carries a screen retaining member 24-passing through an aperture 26. Member-24 has an aperture 28 which receives a padlock 30 which prevents unauthorized removal of the screen. The extra detention bars 22 extending across the more vulnerable area of the window assembly prevent or deter the escape This has been accomof inmates through the ventilating area in case the screen .l4 is torn from its frame Hi. The screen frame It is aligned with the outer margins of the muntin bars l0 bounding the ventilating area so as to prevent a neat appearance.

The closure disclosed inFig. 3 includes a pivotally mounted frame 32 carrying a window pane 34 and held in, adjusted positionby a, link 35 having one end pivotally mounted to the closure frame at 38 and the other end connected to a sliding pivot assembly 46. The pivot assembly 46 includes a stud 4I terminating in a head 42, as best seen in Figs. 4 and 7, that is seated in an aperture 58 in a resilient member 44 which is located in a slot 46 formed intermediate the channel shaped member 48 and the web of the muntin bar I6. Spring member 44 is deflected so as to have one portion 56 edged against the web of the dentention bar I6 and another portion or a pair of spaced portions 52 urged or edged against the bottom of the channel shaped member 48, member 48 being provided with a suitable slot 54 which permits the pivot 40 to slide vertically as the closure is opened and closed. Member 44 exerts sufficient pressure against the sides of the retaining member so as to frictionally hold the closure in any adjusted position. As may best be seen by referring to the disclosure in Fig. 7, member 44 is provided with a pair of squirts or struck-out projections 56 adjacent the aperture 58 which increases the effective bearing surface between member 44 and the head 46. The squirts 56 may be formed by a suitable die provided therefor which causes the metal adjacent the aperture to be ejected from the plane as originally found.

A lock assembly has been provided for locking the closure in closed position. This lock assembly includes the casing 66 provided with a cylindrical bore 62 in which is seated a latch 64 including a cylindrical shank 66 surrounded by a spring 68 having one end abutting the casing 66 and the other end abutting the collar 76. The spring 68 urges the latch upwardly as viewed in Fig. 3.

The shank 66 is provided with a slot I2 through which passes a handle 14 which exerts a camming action upon the loop I8 of the shank 66 to cause the latch 64 to move downwardly as the free end of the handle I4 is moved downwardly as disclosed in Fig. 3. This handle 14 is provided with an eye for the reception of a hook or rod that may be used in adjusting the closure from one position to the other.

The latch 64 engages a keeper 82 that is preferably stamped from a piece of sheet metal and provided with a pair of ears 84 which are welded to member 86 carried by the muntin bar I6 and forming a portion of the outside frame for receiving the closure 32. The keeper 82 is beveled at 88, which beveled surface cooperates with the beveled surface of the latch to permit the closure to be moved into closed position without manually retracting the latch 64.

The bottom of the closure as viewed in Fig. 3 is supported upon a sill 94 that is arranged in hooked relation with respect to the flange 96 of the muntin bar ID. The vertical muntin bar I6 passing through the center of the ventilating area as disclosed in Fig. 1 is undercut at 98 which permits the assembly of the closure in the field or on the job without cutting away the sill to accommodate the detention bars or muntin bars extending across the ventilating area. This arrangement of the sill forms a water-tight union between the frame and the muntin bar II).

In the modification disclosed in Fig. 8 and detailed views disclosed in Figs. 9, 10, 11, and 12, the closure 32 is pivotally mounted on a pair of movable pivot assemblies H6 and H2. The pivot assembly II 6 includes a cylindrical sleeve H4 provided with an internal shoulder H6 adjacent one end which abuts a spring H8 engaging a shoulder I20 upon a guide member I22 which terminates in a channel shaped slide I24 seated over a suitable guide I26 carried by the stationary portion of the closure frame I23. Member 222 has a cylindrical extension I 38 passing through the spring H8 and through the end of the cylindrical sleeve H4. This sleeve H4 is attached to the closure frame I32 by welding or in any other suitable manner. As the upper end of the closure is moved outwardly or to the right, as viewed in Fig. 8, from the full line position to the dot-dash position, the pivot H2 of the closure also swings outwardly and the pivot assembly I It moves upwardly, the channel extension I24 following the guide I26. Link I60 having one end pivoted at H2 has the other end pivoted at 552 to support the closure 32. The pivot at I52 is fixed to member I28.

The closure is retained in closed position by a lock that includes a cam shaped member I46 pivoted at I42 to a support I44 carried by a portion I46 of the closure frame I32. As the handle I63 integral with the cam I46 is rotated the cam shaped portion I 40 engages the keeper I56 when the window is in closed position so as to securely lock it. The keeper I 56 may be made in the same manner as the keeper 82 and welded to the upper cross piece 162 of the frame for the closure.

The sill I54 of the closure frame is arranged in hooked relation with the transverse muntin bar I 6 and is provided with a bight I 56 which cooperates with the flange I58 to make one closure contact and the flanged extremity I 65 of member I5 3 forms the other contact with the closure frame.

From the above description it will be apparent that there is thus provided a device of the character described possessing the particular features of advantage before enumerated as desirable, but which obviously is susceptible of modification in its form, proportions, detail construction and arrangement of parts without departing from the principle involved or sacrificing any of its advantages.
